It's from the movie "Back to the Future". I reduced the dimensions to 80% the original to fit the MK3/S bed and reduced the thickness to 40% to reduce print time.

Print instructions

Prints in 3 colors via filament change: white, orange, and blue (I used black but blue is the color from the movie). The "holes" you see when the white and orange layers are printing are normal and part of the model. I had some lifting of the corners but it was fine and kinda gives it a slightly warn look.
